Dark Power 14 850W ATX 3.1 PSU

The be quiet! Dark Power 14 delivers 850 W of continuous power for high-end desktop builds. It meets the ATX 3.1 specification and carries 80 PLUS Titanium certification with up to 95.6 % efficiency. The fully modular design suits enthusiasts who want clean cable routing and reliable energy delivery.

Modular Build with Silent Wings Fan

A 135 mm Silent Wings fan works alongside an aluminium heatsink to support active or semi-passive cooling modes selectable by a button. Full bridge, synchronous rectifier and LLC topology provide stable voltage regulation across loads. Modular connectors include a 20+4 pin main cable, native 12V-2x6 for PCIe 5.1 graphics cards and 6+2 pin PCIe plugs for broader GPU compatibility.

ATX 3.1 and PCIe 5.1 Interface Limits

The ATX 3.1 standard defines the 12V-2x6 connector for up to 600 W per cable, so a single cable can feed modern GPUs without adapters. Titanium efficiency reduces waste heat, allowing the semi-passive mode to stay silent longer under typical loads. The 10 year manufacturer warranty reflects the confidence in component longevity under these electrical limits.

Kysymyksiä tästä tuotteesta

What does the ATX 3.1 standard mean for the 12V-2x6 connector on this 850W unit?

The ATX 3.1 design includes a native 12V-2x6 connector that delivers up to 600W to a PCIe 5.1 graphics card without an adapter, while the 850W total capacity leaves headroom for the rest of the system.

Will the 17.5 x 15 x 8.6cm case and 2.2kg weight fit a standard ATX tower?

The dimensions match the ATX form factor, so the unit fits any case with a standard PSU bay; allow clearance for the 135mm fan and modular cable plugs at the rear.

How do I switch between active and semi-passive cooling, and what is the common mistake?

Press the button on the PSU rear to toggle modes; the mistake is forgetting to verify the LED indicator matches the desired mode before closing the case.
